Whether the tooltip should follow the mouse as it moves across columns, pie slices and other point types with an extent. By default it behaves this way for scatter, bubble and pie series by override in the plotOptions
for those series types. .
For touch moves to behave the same way, followTouchMove must be true
also.
Whether the tooltip should follow the finger as it moves on a touch device. If this is true
and chart.panning is set,followTouchMove
will take over one-finger touches, so the user needs to use two fingers for zooming and panning.
A string to append to the tooltip format.
Callback function to format the text of the tooltip. Return false to disable tooltip for a specific point on series. . .
A subset of HTML is supported. Unless useHTML is true, the HTML of the tooltip is parsed and converted to SVG, therefore this isn't a complete HTML renderer. The following tags are supported: <b>
, <strong>
, <i>
, <em>
, <br/>
, <span>
. Spans can be styled with a style
attribute, but only text-related CSS that is shared with SVG is handled. . .
Available data are: <dl> . . <dt>this.point</dt>.
this.point.name
, and the value through this.point.value
.this.series.name
.
The HTML of the tooltip header line. Variables are enclosed by curly brackets. Available variables are point.name
, series.name
, series.color
and other members from the point
and series
objects.. .

The number of milliseconds to wait until the tooltip is hidden when mouse out from a point or chart.
Padding inside the tooltip, in pixels.
The HTML of the point's line in the tooltip. Variables are enclosed by curly brackets. Available variables are point.value, series.name and series.color and other properties on the same form. Furthermore, point.value can be extended by the tooltip.valuePrefix
and tooltip.valueSuffix
variables. This can also be overridden for each series, which makes it a good hook for displaying units..
For maps it defaults to '{point.name}: {point.value}<br/>'
A callback function for formatting the HTML output for a single point in the tooltip. Like the pointFormat
string, but with more flexibility.
A callback function to place the tooltip in a default position. The callback receives three parameters: labelWidth
, labelHeight
and point
, where point contains values for plotX
and plotY
telling where the reference point is in the plot area. Add chart.plotLeft
and chart.plotTop
to get the full coordinates.. .
The return should be an object containing x and y values, for example { x: 100, y: 100 }
.
Whether to apply a drop shadow to the tooltip.
Split the tooltip into one label per series, with the header close to the axis. This is recommended over shared tooltips for charts with multiple line series, generally making them easier to read.
CSS styles for the tooltip. The tooltip can also be styled through the CSS. class .highcharts-tooltip
.
